BUG #2
$bbuserinfo is not defined in the routine get_linklistbit - which means that if you are not using forum permissions to determine who can do what, then the code to check whether the current user is allowed to edit their own post doesn't work.
The line which doesn't work is in the links_linkbit template (line 20):
<if condition="$links_permissions[can_edit_link] or $bbuserinfo[userid] == $linkuserid">
and the problem can be fixed simply by declaring $bbuserinfo as global in the get_linklistbit routine in local_links.php - ie. somewhere around line 385 add the following:
global $bbuserinfo;
Works now
